Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed November 23. 1906- Serial No. 344.752.

To all whom it may concern."

Be it known that I, DANIEL G. BOLTON, a citizen of the United. States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Im rovements in Electrical Insulators, of which the following is a specificatlon.

-My invention relates to improvements in electrical insulators in which low tension wires may be securely fastened.

A further object of my invention is to rotect or insulate all parts of the wire, inclu ing the material it is fastened to.

A further purpose of m improved insulator is its adaptability to ifl'erent grades of material to which it may be attached, per- 'mitting installations to be accomplished much more rapidly.

In carrying out the invention in an approved form, whereby one or more wires may e readily attached to the desired house casings or material, disks of insulated material are held in proximity on a driving in or screw. Between said disks is a exible bushing of insulated material, and by the placement of wires between the disks and the insulator forced into its attachment, the wires'will be securely fastened.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevationillustrating-the invention; Fig. 2 is a plan view of Fig. 1 Fig.

3 is a perspective view of the invention; F ig.

4 'a cross-section view of Fig. 3 on the line 44; Fig. 5 is a side elevation, illustrating a double insulator; Fig. 6 is a plan view of Fig. 5; Fig. 7 is a cross-section view of Fig. 5 on Referring to the drawings in which similar letters denote corres onding arts, A designates the material or attac ment, B the wire and C the insulator for attaching.

D as shown in Figs. 5, 6 and 7, representsa double insulator. p

- Details of my invention are shown in Figs. 3 and 4. Insulator C consists of a butt end pin'or screw as C, a disk or plate ofinsulated material C secured to C by means of its orifice C, being insulated by a flexible bushin C is a similar disk as C and-secure,

Pin C is preferably it to be more rapidly driven or attached. Wires as B and B are placed between dlsks C" and C and by forcing pin 0' in' material I and then kept erfectly taut by the method as A be' of wood or soft brick nature, disks C and; are forced together. The soft rubber tube bushing as C permits this to be accomplished. B and B are thereby securely fastened to A, as shown in Figs. 1 and 2, by insulators C and 0 It will be noticed the Wires here illustrated are of the twisted pair variety, and that by tightening these pairs it has a tendency to draw the wires close'to the pin D as shown in Fig. 7. The invention'is nottlimited to the twisted pair or two or more conductor circuits. A single wire can berun and secured to. the insulator by the tie wire method described. I a so do not wish to limit the invention as to themethod of fas'tem'n as pin C A screw, although not as rapi in some cases might be desirable.

In Figs. 5, 6 and 7 are shown the double insulators D and D securin'g two pair of wires as B? and B, and B and B", to the material as T. In Fig. 7 will be seen wires B and B secured between insulated disks D and D and insulated from pin D by D; wires B and B secured between in sulated disks D and l) andinsulated from pin D by insulated bushin D, and also insulated from A by disk Said pin D being permitted to be forced into A by its pointed end D. -The members of the insulator retain their relations by its butt end or head D.- What I claim and desire to' secure by Letters Patent is-,

"1. An electric in'sulatorfcomprising a pin,

disks thereons'pace'd apart, and a sleeve or bushing of flexible insulating material around the pin'between the disks.

2. An electric insulator, comprisinga in having ahead .on one end and constructs at its opposite end for attachment to its support, a series of disks on said in, and sleeves or bushings 'of flexible insu ating material around the ins and'spacing the disks apart.

3. An eiectric insulator, comprising a headed in, wire clamping disks loose on the pin, and a flexible elastic sleeve or bushing around the pin between the disks.

In testimony whereof I aflix my signature in presence of two witnesses.

DANIEL G. BOLTON.
